Idaho ApplicationNove'mber 28, 1952, serial Nol'szaoe j This inventionrelates to a power tool and more"'particularly 'to a portable log peelerfor disbark'ing or peeling timber.

The primary object is to' provide an improved logpeeling machine whichis easily transportable in "'a forest to the locations where it isdesired to peer the bark from logs. I

further-object of this invention is to provide a portable log peelerthatis comparativelylight in' Weightso as to enable such to be readilycarri'e'd'and operated in a convenient manner.

The eonstruction of this invention features the a prime1mover todrive aneccentric which "ea sfes'a' reciprocation of a blade assembly slidablymounted on ia' frame. It is tobe noted thatthe prime mover isresiliently mounted on aframe-so as" to increase the durability of the device while preventing internal damage to working parts- Stillfurtherobject's of theinvention reside in the provision of a portablelog peeler that is ir-e s su t bl hi hly. ef icientnn perati n, im e insoestru t onand an f c t o free; and which is comparatively inexpensiveto produce.

'I'hose', together with the various ancillary objects of the inventionwhich will becom'apparent as the following description proceeds, areobtained by this portable log peeler, a preferred embodiment of whichhas been illustrated in the accompanying drawings, by way of exampleonly, wherein:

'3 Claims. (01. 1114-208) Figure 1 is a side elevational View of theportable log peeler comprising the present invention;

Figure 2 is a bottom plan view of the invention showing the relativepositioning of the various elements of the frame and base in greatestdetail;

Figure 3 is a side elevational view similar to that shown in Figure l,with parts thereof being broken away to show other parts in section forgreatest detail;

Figure 4 is a perspective view of the base and frame members, showing indetail how the various elements may be adjusted relative to each other;

Figure 5 is a perspective view showing the construction of the bladeassembly; and

Figure 6 is a sectional view as taken along the plane of line 6--6 inFigure 3.

With continuing reference to the accompanying drawings wherein likereference numerals designate similar parts throughout the various views,reference numeral [0 indicates an arcuate base panel which is concavedownwardly and which is provided with'side members l2"and. l4. Avv frameincluding leg members it and I8 is providedandthese members it and itare interconnected'at the rearend'by a cross memberZll. Projections 22and 24'ar'eflformed integrally with the leg members It and i8 and'slots26 and 28 are formed in the projections and extend downwardly into thesideframe members it and !8 respectively. Bolt fastjenersitilandfipivotally mount the leg members ilian'd E8 on thejside members [2 and Mof the base {0.

Guides 34 and 36 are'provided and are pivoted at their outer ends to the'legfmembers l6 and I8 by means of bolt fasteners 38' and 40, andadjustablysecured at their inner ends by fasteners 42 and 54 whichextendthrough t'he slots 25 and 28. Carriedby the base it! is a rod G6 whichis threaded at" its upper end as at l8. Therod 46 extends through anaperture in a plate 50 which is provided for securing aprime. mover 52to the frame; The plate .lifl'is heldjin position by means of nut 53 Theother end of the plate 50 is held in'position by a fastenergjit whichalso holds plate 56 which extends over .a portion .of the prime mover"52. Another fastener 58 is pro vided for holding the other end of theplate,56 imposition; fipacedlugs; 60 and 62 support the platetifiin'spacedrelationship to formanopening for the bottom portion of theprime mover 52. A coil spring 64 coaxial with the rod 46 biases theplate 50 away from the base it. This coil spring 64 forms a resilientmounting for the prime mover 52.

The prime member 52 is designed of such size and rating as to readilyenable the device to adequately perform its functions while beingrelatively light in weight. The prime mover 52 drives a shaft 86 whichis keyed to an eccentric 68. The eccentric 68 rides in a bearing ring H]which is mounted within a casing 72 having a crank arm 14 integrallyformed therewith. A suitable Zerk or grease fitting i6 is provided toinsure freedom of movement of the various elements. Secured to the crankarm M is one section 78 of an adjustable rod which includes aturn-buckle Bil for adjusting the size thereof. The other section 82 ofthe rod is secured to a rocker arm 84 mounted on a shaft it which iscarried by ears 88 and 9t secured to an arcuate mounting plate 92. Asuitable grease fitting 5A is provided for lubricating the rocker armand cotter keys as at 96 hold the shaft 86 in position. An arcuateangularly extending guard 98 is provided and a blade it together withthe guard 98 is secured to the member 92 by means of bolts such as I02.The blade I is adapted to slide within grooves I04 and I08 formed in theguides 34 and 36. Handles I 08 and H0 are provided for holding andoperating the portable log peeler. In operation, with the shaft 66actuated by the prime mover 52, the eccentric 08 will cause movement Ofthe bearing I0 and hence a reciprocating movement for the casing I2 andthe crank arm I4. This in turn will actuate the connecting rod sections18 and 82 to reciprocate the entire blade assembly within the slots I04and I06 of the uides 34 and 36. As can be readily understood, thecutting angle of the blade I00 may be changed by adjusting the positionof the guides by means of the nuts 42 and 44. A tie rod II2 forrigidifying the structure has locknuts H4 and H5 for holding the framemembers I6 and I8 in spaced relationship.

Since from the foregoing, the construction and advantages of theportable log peeler are readily apparent, further description isbelieved to be unnecessary.

However, since numerous modifications will readily occur to thoseskilled in the art after a consideration of the foregoing specificationand accompanying drawings, it is not intended to limit the invention tothe precise embodiment shown and described, but all suitablemodifications and equivalents may be readily resorted to which fallwithin the scope of the appended claims.
